It's a reproductive
cycle exclusive for
some mammals,
incluiding humans
What it
involves
Hormones
FSH
Is the first hormone
released. Stands for
Folicule Stimulating
Hormone
Estrogen
It is released by
the stimulating
folicules
Progesterone
It's fred by the developed
folicule, and keeps the corpus
luteum in it's place. It also
makes the liberation of other
hormones above stop
Lutanizing Hormone
It's fred by a high amount
of estrogen, and triggers
the liberation of a
fully-developed egg
Reproductive system
The folicules are developed in one of the
female's ovaries, where from one egg is
released, which lays down in the corpus luteum
(located in the female's uterus) some time after
It's purpose
To develop and release an
egg ready to be fertilized,
and be recieved by the
corpus luteum
Unlike other reproductive
cycles, the mestrual cycle
keeps the individual ready to
reproduce for most of the
time
How it works
1. FSH is released, and the
folucules start developing
2. While the folicules
develop, estrogen is
released
3. A high amount of
estrogen triggers
the releasement of
lutanizing hormone.
4. Lutanizing hormone frees
a single fully developed egg
The developed folicule/s free
progesterone, which stops the
releasement of other hormones
The egg may
be fertilized.
In case it is:
It will then keep releasing
progesterone, which keeps
the corpus luteum in place
The egg, having being
fertilized only once, will
then keep dividing until
a new individual is born
